The cause of the slaves discovery by the farmer is the dog barking at them. What is an effect of the slaves discovery?

One effect of the dog barking at the slaves was they were captured and arrested.

Explanation:

The question is based off an excerpt from the book "The Underground Railroad: A Record of Facts, Authentic Narratives, Letters, & c." In this excerpt, the slaves are in Terrytown, Maryland. They are hiding in the woods and a man walks near them and starts to split wood. He has a dog with him and the dog starts barking at the hidden slaves. The man comes and finds them and is very nice, he gives them advice and offers his barn to hide and get some protection. The man and his daughter cooked for the slaves and they had a big breakfast, they were then told to go rest in the barn and he would show them the way to Gettysburg in the evening. However, one of slaves had a bad feeling and didn't sleep. He stayed awake and heard men outside and the farmer giving them up. They were all captured and arrested after a brief struggle.  

since most of current immigration into the u.s., both legal and illegal, is coming from latin america. it would be very difficult to imagine or rationalize a country my fellow citizens are trying desperately to flee into, would pose a threat to my prosperity or freedom. since the u.s. has a long history of intervention, but no record of permanent occupation, i would not feel oppression is the main objective.  

the largest free trade nation, along with the largest gdp in the world wanting to expand it's economic policy on us, and including us, could only be positive. the u.s. government has no interest in, or way of simply forcing american culture on us. and has no track record of it. other nations that adopted american social culture, or "americanization" did so voluntarily, mainly through the choice of allowing american businesses and u.s. citizens to come into their nations, as free operatives.
